Royals grabbed a 7-6 opener win Friday behind Vinnie Pasquantino's homer and Lane Thomas' go-ahead RBI, injecting momentum despite their 13-19 record and absences like Jonathan India's season-ending shoulder surgery and Carlos Estévez's foot IL. Mariners (16-17) counter with edge in standings but bullpen hit by Matt Brash's fresh lat inflammation placement on 15-day IL; Brendan Donovan (groin) and Victor Robles (pectoral) also sidelined. Castillo's command versus Royals' road woes shapes trader consensus on a tight contest.",
